VULCANIZER.

Patented May 24, 192i.

Application led August 4, 1920. Serial No. 401,099.

To all Awhom t may concern.'

Be itknown that we, EDGAR D. Hos'rLnR, I. J. HAMEL, and CARL H. MATHER, citizens `ofthe United States, and residents of Tipton, in the county of Cedar vand State of Iowa, have invented a new and Improved vulcanizer, of which the following is a full,

clear,.and exact description.

This invention relates to improvements in vulcanizers, and more particularly to vulcanizers designed for connecting the ends of rubber tubes, such for example, as comprise the inner inflated tubesfof wheel tires, an object ofthe invention being to provide a vulcanizer which facilita-tes the vulcanizing :Operation either in the forming of a single or .a double splice.

A further ob]- ect is to-p'rovide a vulcanizer :which is composed of sections readily interchangeable to give the desired shape a-nd dia-meter in accordance Vwith the size of the tube tol be vulcanized. f

A further object is to provide a vulcanizer which is relatively cheap to manufacture,

which can be conveniently used and attached to a tableor support of any proper character and which is` capable of a wide range of utility in the vulcaniziiig operation.

'A further object is to improve upon the i construction disclosed in Patent Number 1.1338569, granted to E. D. Hostler April 27, 1920. y f

With theseand other objects in view the invention consists iii-certain novel features of construction, and combinations and arrangements of' parts, Vas will be more fully hereinafter described and pointed out in the claims. A

In the-accompanying drawings- 40 `Fig-urel-is a viewin side elevation of one section of our improved vulcanizer showing 4the ltubes m section and in-position for making a double splice. Y F ig.-2 is a view.V in side elevation illusv trating. the complete lvulcanizing apparatus .to-form a double splice, showing the same secured toa heating-table or other analogous support.

Fig. 3 is an enlarged top plan view of the v.50. vulcanizer shown in Fig. 2.

Fig. 5 is a plan view illustrating a similar type of vulcanizer shown in Fig.. 3, but so constructed for attachment to the corner of a table.

Fig. 6 is a perspective view of one of the inserts.

Figs. 7, 8, 9, l0, l1, l2, 13, le and l5 are views illustrating modiiications.

'Referring particularly to Figs. l to 6 inclusive, l and 2 represent two sections of one form of our improved vulcanizer. These sections l and 2, when together, constitute in effect a tubular elbow forming two vulcanizing ends 3 and 4 at right angles to each other.l

It will be noted particularly by reference to Figs. l and 2, that the bore 5 of the elbow is of general elliptical shape, and this is due tothe fact that the section l has a recess Vtherein whichv is larger than' the recess of the section 2, and it is to be understood that sec- -tions l and 2 will be provided with various sizes of such recesses so that when two of these sections are together, they will form a -bore or tubular vulcani-zing portions of any lit the end of a table 8 and this'table 8 may have a steam or other heating chamber 9 therein to heat the sections 1 and '2- to the necessary temperature for vulcanizing, and

vwe may employ an ordinary clamp 10 to secure the sections to the table. l is not, however, limited to the particular Our invention manner'of heating the sections as this may be accomplished in various ways.

In Fig. 4 we illustrate a means for eX- panding the vulcanizer to the desired diam- -eter by placing metal inserts ll'between the sections, one'of these inserts being shown `in. perspective in Fig. 9, and it will be noted that theV inserts have extended flanges l2 at their edges with rounded outer surfaces 13 to form a smooth surface for vulcanizing.

In Fig. 5 we illust-rate a vulcanizer with its base portion made with an angular recess lt of such a shape as to lit the corner of the table 3 and provide a clamp 9 located at right angles to the sections. It will also be noted that we provide the sections 1 and 2 with relatively flat base flanges l5 which facilitate the engagement of the clampv and also permits the clamp to hold the sections in 4proper formation for vulcanizing.

The vulcanizing operation carried out on' this form of double splice is as follows: vA rubber tube section 16 is projected through the bore 5 with its ends turned backwardly.l

uponthe outer faces of the tubular sections 3 and 4. The ends of the rubber tube A to be spliced are then positioned over and under the backwardly turned edges of the tube 16, said surfaces 1 being cleaned with gasolene and surfaced with rubberrement, or, in fact, treated by means of any desired process for carrying out the vulcanizing operation when the vulcanizing surfaces are '17 and 18 having in their base portions recesses 19 having flattened lower surfaces to accommodate a clamp 20 to secure the same to a heating table' 21. These sections V17 and 18 are made with tubular portions 22, which, when together, form a continuous tube and the front of the sections are recessed, as shown at 23, to admit one end of a-tube 24 to be vulcanized. The end of this tube 24 is turned over against the outside lof the tubular sections 22 and the other end 0f the tube 24 is located 'over and folded under the same and clamping strips or tape 25 are wound around the same and utilized inconnection with ordinary vulcanizing cement to perfect the vulcanizing operation.

As shown in Fig. 10, the vulcanizer may be expended by the positioning of inserts 11 betweenthe sections, the same as in the preferred form. This form of vulcanizer, shown in Figs. 7 to 1() inclusive, is made fiat to rest directly upon a smooth topped v table' and be securely clamped thereon.

-to"15 inclusive, the vulcanizer 26 is made vintegral with the heating table 27 and conlIn the modification illustrated in Figs. 11

stitutes a single member having a slot 28 in one edge for the reception of an insert 29 corresponding to the insertsA k11, and this insert is removed to allow the section tube to be conveniently removed from the vulcanizer after the vulcanizing operation is completed. In other respects, this' Vvulcanizer corresponds in general shape and contour to the v separable vulcanizer illus` trated in Figs'. 7 to 9 inclusive, with the exception that it constitutes a single part and is made integral with the table and is not of twoseparable members as in Fig. 7.

With all forms of our improved vulcanizer, it will be Vnoted that the vulcanizer itself is heated by means of a table or i't-may be heated from any other sourceand in several of the forms, the size or area ofthe vulcanizing surfaces and the diameter of the sections for accommodating the rubber tubes can be varied to suit conditions. Thispermits of a wide range of utility of the vulcanizer and permits the vulcanizer to be employed with an exterior vulcanizing surface or exteriorvulcanizing surfaces whicliare readily accessible, which facilitate the juncture of the tube sections, and which will permit the vulcanizing operation to be quickly, efficiently and economically performed.

In vulcanizing the sect-ions of the tube, we employ any desired method or material and do not limit ourselves to the particular method or process -as my `invention is intended to cover broadly the vulcanizer itself and any use to which this vulcanizer can be put. v

In Fig.- 14, we illustrate a modification 'in which a steam chamber 30 is formed as-a portion of the base of the vulcanizer itself.

VariousY other V-slight changes might be made in the general form and-arrangement of parts described without departing Vfrom the invention, and hencewe do not limit ourselves to the precise details set forth, but f 'consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims. l/Ve claim: i
